UMBRELLA-RUNNER RETAINER.

SPECIFICATION forming part of Letters Patent No. 427,368, dated May 6,1890.

Application filed February 3, 1890, Serial No. 339,008. (No model.)

To all whom it may concern:

.Be it known that I, JOHN ROSE, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certainImprovements in Umbrella-Runner Retainers, of which the following is aspecification.

One object of my invention is to so construct an umbrella-runnerretainer of wire that it can be snugly fitted to and firmly retained ina saw-kerf or opening made in the stick for its reception, a furtherobject being to insure the firm retention of the back bar of theretainer without interfering with the free play of the projectingspring-finger with which the runner engages. These objects I attain inthe manner hereinafter set forth, reference being had to theaccompanying drawings, in which Figure 1 is a vertical section, on anenlarged scale, of part of the stick of an umbrella or parasol with arunner-retainer c011- structed in accordance with my invention. Fig. 2is a sectional plan view on the line 1 2, Fig. 1. Fig. 3 is aperspective view of the retainer and a sectional perspective viewthrough the center of the stick, showing the recess for the reception ofthe retainer; and

Fig. l is a view of a saw whereby the recess may be formed in the stick.

A represents part of the stick of an umbrella or parasol, and B therunner-retainer, which consists of a curved or segmental back bar a,with upturned portion 1) at the lower end and a notched or offsetportion d near the top, the elastic retaining-finger f projectingoutward at an angle from the top of the back bar and being then bentinward substantially at a right angle to the face of the stick, butterminating in an upwardly-projecting end or hook g, the retainer beingformed of one piece of wire properly bent, as shown in Figs. 1 and 8.

The retainer is adapted to a segmental sawkerf or recess D, formed inthe face of the stick, the back bar of the retainer fitting snuglyagainst the base or bottom of this recess, and the retainer is securedin the recess by means of pins 2' and m, which are passed transverselythrough or partly through the stick, as shown in Fig. 2, the pin '6engaging with the notched or offset portion at of the back bar of theretainer and the pin an engaging with the upwardly bent or hooked end gof the projecting spring-finger of the retainer, so as to not only aidin securing the retainer within the recess of the stick, but also tolimit the expansion or projection of the spring-finger beyond the faceof the stick, as shown in Fig. 1.

The inner portion of the recess D in the stickthat is to say, theportion which receives the back bar a of the retaineris of less widththan the outer portion of the recess, so that while said back bar of theretaine-r fits snugly between the walls of the rear portion of therecess the spring f will play in the wider outer portion of the recess,as shown in Fig. 2, and hence the free movement of the spring-fingerwilluot be restricted even if the stick shrink or swell. The recess maybe readily formed in the stick by the use of a saw such as shown in Fig.4:, this saw having two sets of teeth as and y, the teeth 00 beinglonger than the teeth y and being without set, or having but slight set,so as to form the contracted rear portion of the slot or recess in thestick, while the shorter teeth 1 have such an amount of set as willinsure the cutting of the outer portion of the slot somewhat wider thanthe portion formed by the teeth 00.

Having thus described my invention, I

claim and desire to secure by Letters Patent 1. The within-describedrunner-retainer for umbrellas or parasols, the same consisting of asingle piece of wire bent to form the segmental back bar with notch oroffset near one end, upturned finger at the opposite end,

with the stick having a recess the rear or inner portion of whichreceives the back bar of the retainer and is less in width than the JOHNROSE outerport-ion in which the spring-finger works, i
